HAY AND STRAW BURNER OR ATTACHMENT FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 435,873, dated September 2, 1890.

Application filed May 8, 1890. Serial No. 351,062. (No model.)

To all whom it may concern:

Be it known that we, ANDREW E. EST and MAETHIN O. SAMPSON, citizens of the United States of America, residing at Madison, in the county of Lac-qui-parlc and State of Minne sota, have invented certain new and useful Improvements in Hay and Straw Burners or Attachments forStoves; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable o1 hers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thercon, which form a part of this specification.

This invention relates to certain new and useful improvements in straw and hay bu rning attachments for heating and cooking stoves.

The object of the invention is to provide a casing which may be attached to the front of the stove and form a part thereof, or an independent attaehment for stoves already manufactured; and it consists in a casing having an opening which connects with the body portion of a stove, said casing having on one side a damper and at the opposite end a door or doors for the insertion and removal of fuelcontaining receptacles, and a support for holding the charged cylinders in an elevated position within said casing, the fuel-containing cylinders having openings for the admittance of air to the fuel and exit of the products of combustion, all as will be hereinafter fully setforth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of a hay or straw burning attachment, showing the same applied to a cook-stove of ordinary construction. Fig. 2 is atransverse sectional view of the attachment separated from the stove. Fig. 3 is a perspective view of the fUCl-COllltll'llllg cylinder.

A refers to a heating or cook stove of ordinary construction, to which our improved hay and straw burning attachment is applied, said attachment consisting of a shell or casing of sheet metal provided with suitable means for connecting the same, either permanently or detachably, to the stove in front of the usual grate. This casing B has a transverse opening Z), through which the products of combustion pass into the grate chamber of the stove, and opposite thereto a series of openings 0, which are adapted to be closed by a sliding damper (1. At a suitable point the end sections of the casing are provided with inclined guide-strips e, which are held inplace by rivets or bolts, and opposite these guides c are openings through which the end portionsf of a bail I extend, the outer bar f of said bail being adapted to engage with a serrated barg, so that the inner end f of the bail will be held in the proper position within the casing to maintain one of the fuel cylinders or chambers thereon in the upper portion of the casing B. The lower portion of this casing can have suitable supporting legs or feet, so that the opening I), through which pass the products of combustion, will be located in the proper relative position to said stove.

The fuel-containing cylinders 0r chambers II are provided with longitudinal slots or openings 7L and i and with a central circumterential re-enforcin g ban d t" and a permanently-attached head The end opposite the' permanent-head j carries projecting pins 7a, with which engage slots on the flange of the removable head j, said head also having a een tral opening, through which can be passed a bent rod or poker for agitating or separating the contents of the fuel-chamber.

The cylinders are provided internally with a f ram e-work made up of several bands, to which are attached longitudinal plates Z and 1, which are adapted to be turned within the cylinders, so as to be located over the openings h and i, to close the same when desired. One of these strips is provided with a projecting portion or lug for operating or turning the plates. \Vhen the fuel cylinder is properly supported within the casing, the smaller opening will be opposite the opening 0, while thelarger opening is opposite the opening I), through which the products of combustion pass.

In operation the fuel chamber or cylinder, which has been packed with hay, straw, or other combustible material, is placed within the casing B and supported by the rod f of the bail F, and the fuel is i gnitcd through the damper-opening 0. After the contents of this cylinderlravebeenpartiallyconsumed thesup port F is drawn outwardly from the casing B and permits the cylinder to fall to the bottom of the casing, after which the bail can be slid again inwardly and a fresh cylinder placedin position. It will be observed that the heat and unconsumed contents of the first cylinder will pass upwardly and be utilized, and when the contents of the cylinder in the bottom of the casing have been entirely consumed said cylinder can be removed and repaeked.

This device, as herei nbefore describechwhen in use throws a steady flame and can be recharged by inserting new cylinders without permitting the fire to go down, and it is cleanly, as the ashe can be removed from the cylinders, which can be taken from the stove and recharged. Therefore it is not necessary to lumber up the room within which the stove is placed with a quantity of light fuel as is intended to be used with our invention.

Having thus described our invention, we do not wish to be limited to the precise construction, but reserve the rightto modify the same within the scope and spirit of our claims.

Having thus described our invention, we claim- 1. The combinatiomwith a stove, of acasing B attached thereto or forming part thereof, said casing having an opening through which the products of combustion pass, and an airinlet opening with a damper, a bail F, and a fuel-cylinder within the casing, said fuel-cylinder supported thereby and having openings for the admission of air and the egress of the products of combustion, substantially as set forth.

2. In a hay and straw or light-fuel burning attachment for stoves, a casing B, provided with openings for the exit of products of combustion and the entrance of air, inclined guides or supports, abarf sliding therein, a catch for maintaining said bar in position, and a removable cylinder adapted to be sustained thereon, said cylinder having openings for the admission of air and egress of the products of combustion, substantially as set forth.

3. In combination with a shell or casing, means for securing the same to a stove, a fuelcontaining cylinder and a support therefor so that said cylinder can be maintained in the upper part of the casing, the space below the said support for the cylinder being sufficient to contain a second cylinder, and doors at the end of the casing for the insertion and removal of the cylinders, substantially as set forth.

4. The combination, with the casingB and heating apparatus, of a cylinder within said casing and having longitudinalopenings and an internal frame carrying longitudinal strips which are adapted to cover said openings, either in whole or in part, and a removable head secured to one end of the cylinder, said removable head having a central opening, the parts being combined and organized substantially as shown, and for the purpose set forth.

5. As an improved article of manufacture, a fuel-containing cylinder having longitudinal openings h and t', means contained in said cylinder for closing the openings, and a removablehead having a slotted flange which engages with pins 717 on the ends of the cylinder, substantially as set fort-h.

In testimony whereof we affix our signatures in presence of two witnesses.
